Re: [jira] Commented: (COCOON-2076) Exception when Reloading Classloader

[Jean-Christophe Kermagoret]

Hi,
It works for me if I start jetty through mvn with :
myBlock1 > mvn jetty:run
If I edit src/main/java/demo/MyBean.java and recompile it though mvn, 
class reloading works fine.

But, If I start jetty through Eclipse, and edit MyBean.java, first call 
will produce the following error, while next call is ok and returns the 
right result with possibility to debug code.

Here is the error I get :

org.apache.cocoon.tools.rcl.springreloader.SpringReloader

RequestURI=/myBlock1/spring-bean


     Caused by:
